February 04, 2002, Washington D.C.-- The National Ice Center (NIC) discovered an iceberg newly calved from the Matusevich Glacier Tongue (Figure 1) in Antarctica. The Matusevich Glacial Tongue is a large extension of the Matusevich Glacier from the Antarctic mainland into the northwestern Ross Sea. This new iceberg has been named C-17, and is currently located at 69.06S/157.11E. Iceberg C-17, roughly 11NM long and 4NM wide, covers an area of approximately 58.24 square statute miles. National Ice Center analyst Ms. Judy Shaffier spotted the new berg while performing a weekly analysis of the Ross Sea. Ms. Shaffier located the berg using the satellite image shown above from the Defense Meteorological Satellite Program's (DMSP) Operational Line Scan (OLS) Visible sensor.

Iceberg names are derived from the Antarctic quadrant in which they were originally sighted. The quadrants are divided counter-clockwise in the following manner:
A = 0-90W (Bellinghausen/Weddell Sea)
B = 90W-180 (Amundsen/Eastern Ross Sea)
C = 180-90E (Western Ross Sea/Wilkesland)
D = 90E-0 (Amery/Eastern Weddell Sea).

When an iceberg is first sighted, NIC documents its point of origin. The letter of the quadrant, along with a sequential number is assigned to the iceberg. For example, C-17 is sequentially the 17th iceberg found by the NIC in Antarctica between 180-90E (Quadrant C).

The National Ice Center is a tri-agency operational center represented by the United States Navy (Department of Defense); the National Oceanic and Atmospheric Administration Department of Commerce); and the United States Coast Guard (Department of Homeland Security). The National Ice Center mission is to provide world-wide operational ice analyses for the armed forces of the United States and allied nations, U.S. government agencies, and the private sector.
